[osmo-bts PATCH 1/2] oml: Add support com.ipacces and org.osmocom manufacturer type

[Alvaro Neira Ayuso]

From: Álvaro Neira Ayuso <anayuso at sysmocom.de>

This patch allows to add the osmocom manufacturer id label in the
manufacturer message. Before of this patch, everytime we have added
ipaccess because we had only one kind of manufacturer message.

And I have moved the code that we have used for adding this manufacturer ID
label to the function oml_fom_ack_nack because we only add the manufacturer
Id label in this function now.
